There are no drivers unless you are using a raid drive setup.
Your problem is that the drive isn't plugged in. Go back and push the connector in very hard, it should make a very slight click. Then pull on the cable. If it just slides out, get another cable. Do this to the mobo and the drive..
If this isn't your problem, then go into the cmos and make sure it's set properly, if it is set to boot on the Pata drive, you have to switch over to SATA.
